Airport expansion can have local and global impacts. To achieve net zero emissions in the UK by 2050, the Government’s climate advisors, the Climate Change Committee, allow for no more than 25% growth in aviation passenger numbers on 2018 levels. Yet, current planned and recently approved airport expansions will result in nearly three times this number.
This page provides a summary of those expansion plans that have been submitted as formal applications (although many other airports have said they also have ambitions to expand in the future). We endeavour to update this page as and when we become aware of new airport planning applications or changes to existing applications. If you are concerned about expansion at your local airport and would like information about existing campaign groups in your area, please get in touch with us at email@example.com.
